Some parameters influencing the uptake of industrial Acid blue 113 dye using chitin as natural adsorbent: Equilibrium and Isotherm studies

In the present study, we aimed to evaluate the potentiality of chitin as eco-friendly adsorbent for the removal of industrial dye (Acid Blue 113) from aqueous solutions using the static system under different experimental conditions. The sorption properties of the adsorbent used for the removal of an anionic dye Acid Blue 113 were studied and the results obtained showed that, at initial concentrations of 20 and 100 mg/L at room temperature, the chitin microparticles had a removal percentage higher than 85%. The effect of different environmental factors on the adsorption of AB113 dye was also studied. The results showed that the isotherms were well described by the Langmuir model justifying a monolayer and homogeneous adsorption. Scientifically, it can be concluded that chitin, as an environmentally friendly adsorbent, could potentially be used for the removal of industrial anionic dyes from aqueous solutions.
